HOLLOW-HANDLE ARTICLE.

,epplication filed February 4:, 1924. Serial No. 690,353.

To all it may concern:

Be it lmolwn that L'Bnnrn J. MARSH, a citizen of the United States.residing at Wallingford, in the county of New Haven and State ofConnecticut, have invented a new and useful Improvement in Hollow-Handle Articles; and I do hereby declare the following, when taken inconnection with the a certainin raw a d e characters er reference markedthereon, .to be a full, clear, and exact description of the same, andwhich "said drawin'gsconstitute part of this application, and representin Fig. 1 a view in cleya tiqn of a tableknife embodying my inyention.

My invention relates to an improvement in hollow-handle articles,particularly table knives and forks, but capable of use in themanufacture of a variety of kindred articles in which an implement ismounted in a hollow handle, the object being to greatly re duce the costof labor and material entering into such articles without any impairmentin the appearance thereof.

With these ends in view, my invention cOI1- sists in hollow handlearticles characterized by a one-piece, struck-up. sheet-metal bolsterhaving its edge shaped to be interlocked with the corresponding edge ofthe mouth of a hollow handle.

My invention further consists in a hollowhandle article having certaindetails of con struction as will be hereinafter described andparticularly pointed out in the claim. For the illustration of myinvention, I have shown it as applied to tabl knives for which it wasprimarily designed and for which it is peculiarly adapted, though I donot limit myself to such use of it, as already stated.

As herein shown, the blade 10 and tang 11 of the knife are cutout from asingle piece of wrought sheet-metal of suitable gauge, instead of beingforged from a rod, which is th customary practice inthe manufacture ofhollow-handle table knives. Upon the said bladel mount a one-piecestruck-up, sheetmetal bolster 12, the apex of which is formed with alongitudinal slot 1-3 adapted in length and width to receive the innerend or butt 14 of the tang 11, at the point where the same merges theblade 10 proper. The open end of the said bolster formed with a continuous flange 15, the edge of which is sleeved over and turned into acircumferential locking-groove l6 encircling the mouth of hehcll w han l11 whiell may as any approved construction and design, the said groove16 being flanked its inner side by a bead or fillet 18. Thelocking-fiange 15 may be turned into the said groove in any convenientmanner, such as peening, rolling or by dies.

After the tang 11 of the blade 10 has been passed through theassembling-slot 13 of the bolster 12, the bolster is preferably securedto the tang, and hence to the blade, by a small mass of solder 19,located within it, as shown in Fig. 4, whereby the bolster is secured tothe blade and whereby the bolster-opening 13 is closed so as to preventthe access of any moisture into the handle.

Preferably, though this is not necessary, the handle is filled with somesuitable composition, such as 20, surrounding the tang 11 and fillingthe handle and, as shown, the bolster, whereby the tang is imbedded inthe composition and prevented from flatwise deflection within thehandle, in case of flatwise pressure upon either face of the blade. Tofurther anchor the tang and hence the blade in place, the tang, asshown, and preferably is formed with anchoring-notches 21 receivingportions of the composition, whereby the tang and hence the blade aremore firmly held against longitudinal displacement.

Instead of filling the handle with composition 20, as shown, I may adoptthe common and well-known practice of inserting a cartridge, so tospeak, of fusible metal into the handle prior to the application theretoof the blade and bolster; then, after the same have been assembled, theknife is reversed in position and thehandle heated, causing the fusiblemetal to fuse and re-form itself around the tang, so as to form a solidanchoring mass therefor. This expedient is too well known in the art tocall for illustration.

Heretofore, hollow-handle table-ware has generally been produced byforging the imn. plement-memben such as a knife-blade,

1 terial, by making the same of heavy sheetmetal stock, being enabled todo this by the employment of an independently-forn1ed struck-upone-piece bolster which presents not only an elegant appearance butconstitutes an efiective joint between the implement-member and thehandle of the article, the adjacent edges of the said bolster and handlebeing shaped to be interlocked.

I claim:

The combination with a hollow, sheetmetal handle of unbroken externalcontour between its ends and of the full length of such handles, andhaving a locking-groove formed close to its open inner end, of a short,struck-up, one-piece, sheet-metal bolster having its apex slotted andhaving its flange adapted to fit over the edge of the open end of thehandle, and to be turned into the said locking-groove adjacent thereto,

whereby the bolster and. handle are interlocked at the inner end oil?the latter, an implement having a tang passing through the slot in theapex of the bolster and into the handle, and a body of filling materiallocated within the handle and embedding the said tang for givingstability to the implement.

In testimony whereof, I have signed this specification in the presenceof two subscrih 111g witnesses.
